Abstract

The invention provides an agilawood essential oil vacuum fractionation method. The agilawood essential oil vacuum fractionation method comprises the following steps: preheating a distiller to 110-140DEG C, pumping the pressure of the interior of the distiller to be no higher than 3.8Pa; adding a preheated agilawood essential oil extract in the distiller along the pipe wall of the distiller; controlling a film scraping device with the lower end extending into the distiller to drive a film scraping sheet connected to the lower end of the film scraping device to rotate, scraping off the agilawood essential oil extract from the pipe wall of the distiller by the film scraping device, dispersing the agilawood essential oil extract on the film scraping sheet preheated to 110-140 DEG C, evaporating an essential oil fractionation component from the agilawood essential oil extract, draining to a condenser pipe from the distiller, coagulating into a liquid in the pre-cooled condenser pipe, collecting the liquid, enabling a residue component fractionated from the agilawood essential oil extract to fall off from the film scraping sheet, and collecting the residue component in a residue collecting bottle. The fractionation quality is good, the fractionation efficiency of the essential oil is high, and the method has a higher practical value.

Description

technical field [0001] The invention relates to the technical field of essential oil fractionation, in particular to a vacuum fractionation method for agarwood essential oil. Background technique [0002] Agarwood is the resinous wood of Aquilaria sinensis (Lour.) Gilg, a plant of the family Thymelaeaceae. Distributed in Guangdong, Hainan, Guangxi, Fujian and other places. Agarwood essential oil is distilled and extracted from precious agarwood, which is the essence of agarwood. Agarwood essential oil has multiple effects on the human body, such as: improving the aura, relieving stress, sleeping and anti-depression, regulating the body and mind, and promoting body metabolism. A few drops of agarwood essential oil can be added to the hot water for soaking feet to achieve the purpose of promoting blood circulation and meridians, and can also achieve the effect of removing beriberi and foot odor. Due to the non-renewability of natural agarwood, the refined agarwood oil is ev...
